How many users have SLI/Crossfire?

I recomend if you you want to have a QSLI to by a hydrosystem to cool them so you could overclock them to real GTX580 or even more. I am thinking to do so in the near future.

Otherwise you will have real big noise from the fan system and you cannot of course overclock them as if you do, so you will probable burn the cards......

But be aware:
1. I have combined the cards with a i7 X980 and 12g of RAM. So the results that I am getting from the benchmarks and games are more than good, always in triple monitor setup.
2. I don't know you system specs so I suppose that you have one and you want to buy a second one. For my point of view do it only if you intend to play the game in a triple monitor. When you play a game in a single monitor even in a resolution 2560x1440 one card it is enough to do the job (even more than enough). QSLI in fulHD and hiRES resolutions has no big diference from a dualSLI

With respect

Each core has 1.5 gb but u will only have 1.5 gb overall and not 1% more, still to few vram to run sufficient.

So it is everything, but not 4 cards running slightly on lowrr performance. They are tunning at very low performance. And the expensive ddr5 vram is just wasted, not having any influence. Expensive way. It is like buying another 100gb ddr3 ram just to look good, but with no benefit. Sorry, but do not say, that sli only has small downgrade effect on the cards. It has a very big one!!!!!

Not possible. Maybe you mean 6990?

The thing that prevents me from going to an SLI/X-fire setup is all this talk of micro stutter.
The last thing I need is to spend a healthy amount of money on a dual card setup and experience micro stutter. I know many claim never to have experienced it, but others have.

How many users here with dual cards have experienced this phenomenon?

I've never it and I doubt anyone would ever use either if they did but I only use Nvidia GPUs. My last ATI card was a Rage Pro 8mb.

I have dual 580s and never experienced any stutter. SLI is working for me fairly good now although no noticeable jump in FPS. 2D sprites like dust, smoke, explosions and grass can be a big FPS hit, not sure why that is ?????

And you won't until nVidia does a driver to activate it. I look forward to an fps boost when they do.

Not so much a stut..tut...tut...er more like render lags down low flying very high detail.X-fire does make a conciderable difference to performance now.

Probably by you are correct if you are looking to the ''cold numbers''. But the truth I think it is somewhere between the words you wrote and the fact that by the time that I bought the cards they cost me a lot less than 4 gtx580 (to be exact lesser than 3) and little less than 4 gtx570 comparing to which they have better perfomance. So I think that always you have to balance between the things you want and the way to have the most of them.

Just want to say, that there is a main feature on videocards, which could always destroy your intention: nowadays, it is about vram as texture load and the games itself require this to run extremely fast. So, you can do sli and max out some values and your graphics power, but as soon as you have insufficient 1.5gb cards, you simply cannot compete with the others. You want to play in higher res and with more detail. And if a game like bf3 require at least 1.5gb for sufficient running and you buy quad sli with 1gb vram, you will have this bottleneck. You cab add 100 cards with 1gb and it will be again only 1gb vram, when u sum it up.

So it is not inbetween. Your 4x 580 with 1.5 gig with not have a single bit more thab 1x1.5 gb. That is sli and that needs to be changed. Otherwise ab upgrafe is simply getting by far more expensive than a new single card! Here in clod, you can add 4 more 580 and still have the bottleneck and you will not run a real high resolution or a triple monitor rig sufficiently. And to fire 1 card on 100% and effectively (with the vram issue integrated) 60 - 70 % of all other 3 cards is not very intelligent. It is like buying four cars and directly throw one into trash. Additionally you pay for fuel for 4 cars, although 3 of them are full. You leave this additional fuel untouched forever, except one third which you will burn in your garden for nothing as well.

Sounds weird and funny, but noone with the intention to upgrade an old system with sli additional card should ever think about that. It is simply for enthusiasts, who pimp their goid running rig with an second card for an extra bang (to run for example higher res or triple monitors). These guys know, what they have to do and they know, that sli would only work after having a look over the current card and its abilities. Would it be to slow or of a too low vram for example, they wouldn't use it to built up a sli rig. And I just want to tell these facts to you, before you all think, that it is a good idea to built up an sli with 2x 460, because it is cheap. It is simply a bad idea for most of the innocent guys out there not kbowing the facts of sli and what you have to think about it or how to validate

Sorry, but please do not all buy sli because some bf3 kiddies tell you. It could happen that you are very upset about your invest.
